The Democratic Republic of Congo’s foreign minister Therese Kayikwamba Wagner has urged soccer clubs Arsenal, Bayern Munich and Paris St Germain to end their "blood-stained" sponsorship agreements with "Visit Rwanda" following the worsening humanitarian crisis in the country.

Arsenal have been accused by the government of the Democratic Republic of Congo of a “bloodstained sponsorship deal” over their shirt-sleeve agreement with Rwanda, in light of the recent invasion of Congolese territory.

There has been fierce fighting as Rwanda-backed M23 rebels advance towards the second-largest city in eastern Democratic Republic of Congo, marking a further escalation in the region's conflict. M23 fighters have been moving south, towards Bukavu, the capital of South Kivu, after capturing the largest city in the region, Goma.

Rwanda's ally Uganda, unhappy about another rebel group in DR Congo that threatens its security, has also been accused of helping the M23 - with its officers also spotted at Tchanzu. The UN experts say Uganda has also supplied weapons, hosted rebel leaders and allowed cross-border movements of M23 fighters - accusations Kampala denies.
